Watch: Kurt Cobain: Montage of Heck Trailer

The documentary, which premiered at Sundance earlier this year, is the first "authorized" documentary on the life (and death) of Kurt Cobain, with full support of his daughter Frances Bean and widow, Courtney Love. It screens this week at SXSW in Austin.

According to the official synopsis;

"Experience Kurt Cobain like never before in the first fully authorized portrait of the famed rock music icon. Director Brett Morgen expertly blends Cobain's personal archive of art, music, and never-before-seen home movies with animation and revelatory interviews with his family and closest confidants. Following Kurt from his earliest years in Aberdeen, Washington, through the height of his fame, a visceral and detailed cinematic insight of an artist at odds with his surroundings emerges."

And the film's director, Bret Morgan, revealed that the film's soundtrack will include a 12-minute acoustic song by Cobain.

The film will premiere May 4 on HBO. Watch the trailer below:
